Thats a tough one since the computer is older (it came with Vista). There are some processors that could work with this motherboard, just search for AM2+ socket processors (or AM3 I heard works with that socket as well). I only saw a couple on newegg.com. It might be a good idea to get a new motherboard+processor, and use your existing hard drive and graphics card. Note that with a motherboard upgrade you will have to generalize your drivers before you switch motherboards so it will pick up all your peripherals.
